README
Measure latencies for Shovel indexing a new block and Daimo API pushing an update
via TRPC `onAccountUpdate` subscription. Treat new block notification as baseline.
To trace TRPC, ensure that the server sends update on every block in `onAccountUpdate`,
and not only when there are new transfers for a user.
# Environment
- Daimo API server running on the same machine.
- RPC Provider same as one used on staging Daimo and in the same geo region (<5ms latency)
- Postgres database running in different datacenter but in close geo proximity (~20ms laty)
# Collect data
Run those commands in parallel
```
deno run -A --unsafely-ignore-certificate-errors rpc.js > data/rpc.tsv
deno run -A api.ts > data/api.tsv
deno run -A --unsafely-ignore-certificate-errors pg.js > data/pg.tsv
```
# Analyze data
```
$ duckdb < latencies.sql
